I understood that Jewish belief was that life began when the first breath was drawn.

Leaving aside the fact that this position is contrary to Jewish law, I doubt it will "create", though perhaps give antisemites something to yap about. It's my understanding this relates to pro abortion protests underway in about 50 cities nationwide, including Warsaw. I noted the populations of Jewish Poland below. Antisemites would have to explain just who, in a nation of around 38 million, over 90% Catholic, the protestors are. 3,200 Jews, men, women and children, aren't a significant number of protestors. That said, the statement is obviously secular in nature as abortion on demand is inconsistant with Jewish law.

Not exactly.
But Jewish law on abortion is extremely clear, and that is: abortion is forbidden except when the life of the mother is in clear and imminent danger (e.g., an ectopic pregnancy).
